Best Buying Tips

There are myriads of dumbbells on the market and it can be difficult to choose the one that meet your demand. Here are some tips on what you should take into consideration when buying your own dumbbells.

The most important tip is that, do not purchase adjustable dumbbells which are expensive and not durable enough for gym.

Let’s move on.


It is a key factor when you consider buying fitness equipment. Thus, it is very essential to think about and do some research on what the material used in dumbbells. Nowadays, many materials can be used in producing dumbbells. But if you choose the dumbbells made with rubber, you should know that any products made with rubber has an odor. Besides, you should choose the material that best suits your health and training. Besides, you may also want to do your fair share for the environment so it is worthwhile to take the environment into consideration. Rubber dumbbells now have become popular because they helps reduce the discomfort of dropping dumbbells.

Weight Range

Weight is another important factor that gym owners need to consider because different trainees have different training goals. Generally speaking, lighter dumbbells are the most ideal choice for beginners and people who want to start from a light workout. Therefore, as the gym owner, you should consider the needs of all of your customers. We suggest you buy the full sets from the lightest to the heaviest for your members to exercise with.

Grip And Handle

Dumbbells can be heavy and you do not want to see them slip away from trainees’ hands. The grip and handle of dumbbells are very important because they help your customers prevent injury and slipping. Most metal handles are equipped with a cross-hatch design which gives trainees extra grip, particularly if their hands get sweaty easily. And heavier dumbbells with a stable and rough grip are even more essential.


The durability of fitness equipment and the quality of fitness equipment can be very essential for a gym, because fitness equipment with a longer lifespan helps save money and release the financial burden of the gym owner. Beside you should also consider the after-sales service in order to avoid unnecessary trouble.


Fixed-weight hex or round dumbbells are those with two weights fixed onto either end of the handle. It has a pre-designed weight that cannot be removed or adjusted, which requires you to buy a set of dumbbells to offer all the weight increase for your training. And that type of dumbbells can be inconvenient for home gyms.
